CURTAIN-FIXTURE.

Speccaton of Letters Patent No. 13,588, dated September 18, 1855.

To all whom t may concern:

Be it known that I, PETER H. NILEs, of Boston, in the county of Suffolk and Oom*- monwealt-h of Massachusetts, have invented new and useful Improvements in Shade and Curtain Fixtures; and I do hereby declare that the following description, with the accompanying drawings, forms a full, clear, and eXact specification thereof.

The same letters representlike parts in all the drawings, which are numbered to correspond with the descriptions.

My improvements are characterized, constructed and operated as follows: This is an improvement on the self-adjusting spiral spring xture. It consists in making one bracket with a plain hole large enough to receive one end of the roller and allow it to turn easily and the other bracket with a hole bored with a double bit of two diameters the deepest part being the smallest and in the center for the spring pin on the end of the roller to enter and turn in, and the shallowest part being larger to receive the end of the roller turned down to lit it. Then the spring pin is inserted into its place and pressed in far enough to allow the other end of the roller to slip into its hole in the other bracket, the spiral spring then acts and opens a space suticient for the cord to wind in between the bracket and the shoulder of the roller turned down as aforesaid, thus saving the space of one half of the spool on one end of the roller and the whole of the knob or cap on the other end in the common Xture, which space may be used for widening the curtain, but when saving of space is not important, a single or double headed spool may be used on the end of the roller and be fitted to said hole of double diameter, with thespring pin. This improvement is shown in Figure 3, in which F represents in section the bracket with the hole of double diameter and the spring pin and the single headed spool on the end of the roller iittedin as described.

I claim- The combination of the bracket having a hole of double diameter with the spring in and the roller end either with or without a spool thereon fitted to correspond to said hole and dispensing with the knob or cap on the other end of the roller substantially as above described.
